Youngun!
I seem to be following you around the board
. I just happen to have the Sept. 2002 issue of Shooting Times Magazine which talks about "shooting roundnose, spitzer, and boattail hunting bullets for drop". The author used a 30.06 (because of it's popularity) in an acutal test. He used a rifle with a 26 inch barrel and zeroed each load at 100 yards. He then shot at 300 yards to compare drop. He matched velocities between bullets to be nearly the same in each weight class.
From personal experience, boattails have less contact surface area in the barrel. They may shoot better or worse in any paticular rifle. I have one rifle that loves them, and another that doesn't. Out to 300 yards, it doesn't seem to make too much difference. They do get more money for them though.
